The photoelectric effect was the observation that electrons emit from metals when light is shined upon them.
The photoelectric effect proves that waves do not add.
Einstein discovered photons – particles of light that have no mass but have a lot of energy. They collide with electrons on the surface and emit them. They are big enough for them to surface.
Increasing the frequency of light increases the energy of each photon so that the ejected electrons would have more energy but the number of electrons would not increase. Some electrons have more energy that isn’t used when they leave the atom.
Increasing the intensity of light increases the number of photons but does not change the energy of each individual one or so more electrons are ejected with the same energy.
The light waves give electrons energy to hop.
Light is wave particle duality because electrons are so tiny that they do not behave like classical particles.
Group 2:
The photoelectric effect is when light is shown on a metal and ejects the electrons. When a high frequency light ray hit the metal high energy electrons were released but the number of electrons stayed the same. When a high intensity ray of light hit the surface of the metal more electrons were released but the energy level did not change. It creates an electric circuit with the light hitting the medal and the electrons bouncing off with energy.
Group 3
- It’s a contradiction because when you push electrons they are supposed to jump from ring to ring from the atom but if there are waves they add up energy but there wasn’t enough energy to push the electrons
When they thought light would push the electrons it didn’t work out and they assumed light had to be particles
Group 4:
Photoelectric Effect: The Photoelectric effect is when light hits a piece of metal and electrons are projected off of the metal. The electrons get energy from the light which causes them to get enough energy to be able to bounce off of the atom. Electrons get energy from the light and bounce from ring to ring till they bounce off of the atom. Einstein found out the greater intensity of light the amount of electrons increase but the increasing of the frequency of light increases the energy of the electrons. Light is a particle because the bigger the photons are then the more energy they give the electrons but if the photons are not big enough the electrons cannot get off of the atom.
Group 5:
Photoelectric Effect:
This process demonstrates light hitting a solid metal and electrons deflecting off. We know the electrons are being balanced off because electrons are the source of electricity and a circuit can be created with ammeter, which tells the voltage (how many electrons there are) deflecting off. However, ejecting the electrons is inconsistent which showed light couldn’t be a wave. Electrons have a certain intensity before they can leave the metal but the light needs enough energy to begin with, otherwise the electrons won’t be able to leave the metal. Scientists contemplated the ideas that higher light frequency increases the energy of electrons but not number of electrons and higher light intensity increases the amount of electrons but not the energy. Einstein explained since waves will add up, the electrons will not leave the metal until it has enough energy; however this doesn’t happen in this example. Photons, which are light particles, charge electrons with high enough energy (frequency) to escape and if the light intensity is high, it gives charges the electrons enough to escape.
Group 6:
Light pushes electrons from the surface of a solid.
It was determined that electrons cause electricity when they come off a piece of metal.
The higher the frequency of electrons, the higher the energy of the electrons.
The higher the intensity of electrons, the higher the number of electrons ejected.
They believed that light was a particle because if it was a wave then the electrons wouldn’t have enough energy to jump from ring to ring and would have to wait for another light wave to come.
